<p>A vehicle 10 comprises front and rear wheels 12, 14, a passenger cell 16, and an engine 26, where the engine is located entirely aft of the foremost extent of the passenger cell. The engine has a cooling circuit and a radiator 28 which is in fluid communication with the cooling circuit. The radiator is located aft of the front wheel centres and in an airflow path that extends from an underside of the vehicle to an exit 36 on a rear face of the vehicle. In use, this arrangement is designed to place the radiator close to the engine and by locating the exit on the rear face of the vehicle it opens into a low pressure region 44 created behind the vehicle as it moves through the air. Preferably, the exit is located on the rear face at a height such that at least part of the exit is above the rear wheel centres, to place the exit at a position with sufficient air pressure differential. The flow path may be partially or fully ducted, and/or it may be defined between other items such as the underside of the passenger cell and an upper surface of the engine.</p> |
